Ethanol and Lactic Acid Fermentation

A type of cellular respiration that happens when there is no final electron acceptor. Depending on the organism, ethanol or lactic acid will be produced. It is less efficient than aerobic respiration, but it still creates energy for the cell.

Lactic acid fermentation is what type of process?

User Avatar

Asked by Wiki User

Lactic acid fermentation is an anaerobic process. This means that lactic acid is produced in the absence of oxygen. This usually occur in bacteria cells but can also occur in muscle cells.

Why do you have to breathe to produce energy?

User Avatar

Asked by Wiki User

You breathe in fresh air which contains the oxygen you need. you get rid of carbon dioxide when you breathe out stale air

Lactic acid fermentation occurs in what?

Asked by Wiki User

The fermentation of milk occurs to form curd, of course lactic acid is released.

What is the economic importance of the process of fermentation?

it makes the dough rise, and then the bread would be fluffier and would also taste better. hope this helps. :) XD

What is the negative control in a fermentation lab?

User Avatar

Asked by Wiki User

Howdy there!

Negative control for a fermentation lab should have the substrate in the vessel, and it should be very sterile so no contamination doesn't happen (make sure to label them vessels well). Secondly, the negative control vessel should not be inoculated with the microbe, like yeast, in it at all because you want no response. If there is a response, it could be contamination or you mistakenly inoculated with the microbe which fermented the substrate.

Hope this helped you plenty! 😄

What statement best describes lactic acid fermentation?

User Avatar

Asked by Wiki User

Sugar from plant material is converted into ethanol and carbon dioxide by fermentation. The enzymes found in single-celled fungi (yeast) are the natural catalysts that can make this process happen: Unlike ethene, sugar from plant material is a renewable resource.

What does Phosphoglycerate kinase do?

Asked by Wiki User

Phosphorylase is an enzyme which joins with Glucose-1-phosphate together to make larger starch molecules. it is an example of synthesis (a joing together enzyme)

What three things does alcohol fermentation create?

User Avatar

Asked by Wiki User

There are three things. They are CO2,ethanol and ATP

What do both lactic-acid fermentation and alcoholic fermentaion produce?

User Avatar

Asked by Wiki User

Both alcoholic and lactic acid fermentation produce pyruvic acid (pyruvate), as an intermediate substance.

What conditions is lactic acid fermentation?

User Avatar

Asked by Wiki User

Simple answer:

Under the condition of strenuous exercise with inadequate oxygen supply. ;D

Complicated answer:

When your muscle cells are asked to perform work at an easy relaxed pace they take in glucose, fructose or sucrose plus oxygen from the blood, and using the "Aerobic Respiration" method, they generate cellular motion energy without releasing lactic acid.

Read more about that amazing process here:

http://en.wikipedia.org/wiki/Cellular_respiration#Aerobic_respiration

HOWEVER when your muscle cells are asked to perform strenuous work at an over-extended pace, (like your running away from a bear who wants to eat you). Then the oxygen becomes in short supply. There is not enough oxygen supplied by the lungs to increase output under the "Aerobic Respiration" method.

So, the muscle cells, knowing that they will die if they don't produce more energy, have a Plan - B. They can create massive amounts of energy without oxygen with the drawback of creating lactic acid. But that's fine, they will clean up that mess later. They start using an "Anaerobic Respiration" method.

Read more about that here.

The muscle prefers to make energy using "aerobic methods", but in extreme situations, your muscle cells have a "turbo" option: "Anaerobic_respiration".

Answer #2:

Your muscle cells will undergo lactic-acid fermentation (Creating cellular energy anaerobically) when there is not enough oxygen in the blood to create cellular energy in the preferred aerobic way.

Why does lactic acid build in certain areas of muscles?

User Avatar

Asked by Wiki User

It Builds up when you exersize and muscle cant get enough oxygen. its another way of creating energy.

What raw material is not needed for fermentation to happen?

User Avatar

Asked by Wiki User

you have to go get a job

and

go ask your science teacher to help

  1. if your teacher dont know the answer go to your house and look for the answer
  2. then come and go to the mall if you got the answer

How are alcholic and lactic acid fermentation different?

User Avatar

Asked by Wiki User

lactic acid fermentation helps make yogurt, cheese, and it also occurs in muscles which is why you may get that burning sensation in your legs while excersizing. Alcoholic fermentation makes wine and bread using yeast.

What is a similarity between alcohol fermentation and aerobic respiration?

User Avatar

Asked by Gp15567395742514

The similarity is they both will make ATP (energy) as a product though the alcohol fermentation makes very less.

Why is ATP better than glucose as an immediate energy source for cell metabolism?

User Avatar

Asked by Wiki User

Creatine phosphate is a better source of quick energy than glucose because in thermodynamic scale of energy potential Creatine phosphate is a super high energy phosphate compounds which has higher standard free energy of hydrolysis than that of ATP and can give its high energy phosphoryl group to ADP to generate ATP which is used to biosynthesis Glucose. so creatine phosphate stored in muscle is quick enery source to produce ATP than glucoe.

What would happen if lactic acid fermentation did not occur in muscles?

User Avatar

Asked by Wiki User

We would die because are body would not be making ATP and are body's could not hold down yeast

What are the balanced chemical equations for lactic acid fermentation?

User Avatar

Asked by Wiki User

An organic acid with the chemical formula CH3CH (OH). COOH. Lactic acid is a product of anaerobic glycolysisLactic acid system An anaerobic energy system in which ATP is manufactured from the breakdown of glucose to pyruvic acid. The acid is then converted to lactic acid. High-intensity activities lasting up to about two or three min use this energy system during which the reduction of nicotinamide adenine dinucleotide (NAD) is coupled with a net production of two ATP molecules for each glucose molecule metabolized.

Can we stay in fermentation forever?

Asked by Wiki User

The process of fermentation releases carbon dioxide, so we can not stay in fermentation forever.

How does the process of fermentation differ from the process of respiration?

User Avatar

Asked by Wiki User

while respiration implies air, fermentation is an anaerobic (no oxygen) process.

What is Ph of lactic acid having pka of 4.4 when its 20 percent dissociated?

User Avatar

Asked by Wiki User

Using the Henderson-Hasslebach equation, pH=pKa+log([base]/[acid]), we can determine the pH as follows:

pH=4.4+log([0.8]/[0.2])
pH=4.4+log(4)
pH=4.4+0.60
pH=5.0
